IndexOutOfBoundsException in my Android Listview adapter

Question

I keep getting this IndexOutOfBoundsException, but can't seem to figure out what's causing it. My listview has an adapter with a list of objects, and the objects are removed based on a timestamp. The removal is done inside the getView method. Once an item is removed, I call notifyDataSetChanged().

The full source code is available on github, and here's a link to the listview adapter code: https://github.com/kenneho/run-for-the-bus/blob/master/app/src/main/java/net/kenneho/runnow/adapters/TravelsAdapter.java

This is the beginning of the stacktrace I keep getting:

java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0
at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:255)
at java.util.ArrayList.get(ArrayList.java:308)
at android.widget.HeaderViewListAdapter.isEnabled(HeaderViewListAdapter.java:164)
at android.widget.ListView.dispatchDraw(ListView.java:3307)
at android.view.View.draw(View.java:15213)
<snip>

I see that often the position-value within getView can get as high as six or seven.

Can anyone here spot the bug? Any help will be appreciated.

Finally the bug is fixed. First, I refactored the code as suggested by @Selvin. Second, I added a "removecallback"-statement to stop any Runnables before creating new ones:

// Make sure we stop existing timers, if any.
timerHandler.removeCallbacks(timerRunnable);

timerRunnable = new Runnable() {

   @Override
   public void run() {
      removeExpiredTravels(myAdapter);
      myAdapter.notifyDataSetChanged();
      timerHandler.postDelayed(this, 1000);
   }
};

timerHandler.postDelayed(timerRunnable, 0);

Thanks for helping me tracking down this bug.
